The long handle makes it very comfortable to use since it requires very little effort to keep it depressed. This is the best sandblasting gun I have used and it is worth the price. This Skat Blast Sandblasting Gun is the gun in my cabinet. It is not quite as efficient as a dedicated soda blaster, but I have used it to soda blast 100 pounds of nuts and bolts with no problems.
Another great thing about these sandblasting guns, is you can stick the pick-up tube in baking soda and use it soda blast. This style of sandblasting gun is cheap and gets the job done. As the air passes through the sandblast gun, it uses a venturi effect to suck the media through the media hose and force it out of the nozzle of the gun. One is an air supply line from your air compressor and the other is a media pick-up hose which is a larger diameter hose that you can stick in a bucket of media. A siphon feed sandblaster generally looks like a gun, it can have a trigger or a foot control pedal.

See How to Dry Compressed Air for more info on this.Īs far as sandblasters go, there are 2 main types: "Siphon Feed" and "Pressure Pot". If you are blasting with oily, moisture laden air, then this will likely cause defects in the finish. Another downside to this is, is that when powder coating, you want your part to be perfectly clean after sandblasting. Otherwise the media mixes with the moisture and causes frequent clogging. Sandblasting also requires very dry air from the air compressor. The general rule is to buy the most compressor you can afford, but if you can only afford a 5 gallon pancake air compressor, keep saving! I personally use a Husky 60 gallon air compressor that puts out which is enough to blast continuously, however the I do stop to give the compressor breaks. Air compressors are not cheap, even used, so while a large compressor like that would be ideal, you CAN make due with a smaller compressor.
To see what kind of compressor you need or to see if your compressor is up to the task, take a look at " Choosing an Air Compressor" Many DIY sandblasters out there state that you need at least a 2 stage 80 gallon air compressor that puts out at least to sandblast. To use a sandblaster, you will need an air compressor to supply you with this high pressure air, and a sandblaster consumes a lot of air so you will need a decent sized compressor. However, these require that you wear some personal protection equipment to keep your skin, eyes, and lungs safe. There are also sandblasting guns and nozzles that can be used outside of a cabinet, such as in a blast room, or just anywhere outdoors. This sandblasting gun can be placed inside of a sealed cabinet to contain all your media and allow you to reuse it. When this media hits the metal, it can knock off rust, scale, dirt, paint, or other coatings giving you a clean bare metal surface. Imagine that this picture is a microscopic view of a powder coated surface and decide which surface would allow the coating to adhere better.Ī sandblaster uses high pressure air to propel sand or other media. Without a surface profile, powder coating can just peel off the surface, this is called delamination. While sanding with sandpaper can give your object a profile, it is much more tedious and sometimes difficult for complex items, a sandblaster creates a uniform textured finish all over the entire surface of your part, and in places that no sandpaper can reach. A profile allows the powder coat to seep into all of these high and low points which allow it adhere to the part much better than if the metal was completely smooth. These scratches create high points and low points in the metal which increases the available surface area for paint and powder coat to stick to. Think of sanding a piece of metal with sandpaper and you see the thousands of little scratches that it leaves. The main advantage that sandblasting offers besides the deep-cleaning of metal when preparing your items for powder coating is that it gives the item a surface profile or "tooth".
